Julius Volz 008314b5a8 Ensure that all extracted samples are added to view. 
The current behavior only adds those samples to the view that are extracted by
the last pass of the last processed op and throws other ones away. This is a
bug. We need to append all samples that are extracted by each op pass.

This also makes view.appendSamples() take an array of samples.

Julius Volz 63625bd244 Make view use memory persistence, remove obsolete code. 
This makes the memory persistence the backing store for views and
adjusts the MetricPersistence interface accordingly. It also removes
unused Get* method implementations from the LevelDB persistence so they
don't need to be adapted to the new interface. In the future, we should
rethink these interfaces.

All staleness and interpolation handling is now removed from the storage
layer and will be handled only by the query layer in the future.

Matt T. Proud 978acd4e96 Simplify time group optimizations. 
The old code performed well according to the benchmarks, but the
new code shaves 1/6th of the time off the original and with less
code.
